Fixing a Scipy error

[SamFerracin]

Context: In the latest MrM release, scipy was unpinned. Syncing the develop branch with this latest release causes pytest errors due to improper type handling on scipy's side.

Description of the Change:

• Syncing develop with latest main
• Fixing scipy error by adding a dtype parameter to math.sqrtm so that it never returns arrays of an unsupported type (specifically, complex256)
• Updating dependencies
• Modifying the CHANGELOG in preparation for release
